Mesa PD: Threat written on bathroom mirror; school evacuated

A Mesa school was evacuated Friday morning after a bomb threat was found in a bathroom.

Mesa Police Department spokesman Steve Berry said someone wrote about a bomb on a mirror with a marker in a boy's bathroom at Dobson High School on Thursday. The school resource officer and Mesa police checked the school but didn't find anything.

The same was the case Friday morning. Then mid-morning, a boy in a classroom commented about the bomb threat. His classmates and teacher heard and the boy was detained. Police evacuated the building.
